Partial Reconfiguration of FPGAs is a compelling design concept for general purpose reconfigurable systems for its flexibility and extensibility. Despite the significant improvements in software tools and support, the Xilinx partial reconfiguration design option has a reputation for being an expert level flow that is difficult to use. In this tutorial we will show that it can actually be quite simple. As a case study, we apply Partial Reconfiguration to the Simple Interface for Reconfigurable Computing (SIRC) toolset. Combining SIRC and partial reconfiguration makes the idea of general purpose hardware and software user systems deployed on demand on generic platforms viable. The goal is to make developers more confident in the practicality of this concept and in their own ability to use it, so that more will take advantage of what it has to offer.
